Attention to the use of LNG storage tanks: Shandong Zhongjie Natural Gas Storage Tank Manufacturer

Description :

　　Liquefied natural gas storage tanks (also known as LNG storage tanks) are commodities that store liquefied natural gas, special equipment, Class III pressure vessels, and 06Ni9DR data. Through non-destructive testing, hydrostatic pressure testing, on-site inspection by the Skills Supervision Bureau, pressure vessel inspection certificates are issued, and external rust removal and painting techniques are completed. Below is Beijing Jinhaixinlow-temperature storage tankLet's introduce the precautions for the use of LNG storage tanks, as follows:

　　1. LNG storage tanks cannot be transported with liquid, and the LNG liquid in the tank should be discharged when it is not in use for a long time.

　　2. For storage tanks with double root valves, the valves close to the tank should be normally open.

　　3. When unloading, it is advocated that the maximum filling capacity of LNG storage tanks should not exceed 90% of the useful volume (the manufacturer provides 85% -95% of the geometric volume), and the remaining usage should not be less than 10%.

　　4. When there is a large amount of long-term "sweating" or frosting in LNG storage tanks, and the pressure continues to rise rapidly, the vacuum failure should be considered and urgent measures should be taken, such as manual pressure relief and handling of LNG liquid in the tanks.

　　5. When the pressure of the LNG storage tank is high, it is often assumed that there is a problem with the LNG storage tank. The leakage heat and storage time of the entire system should be considered. Usually, when the pressure exceeds 1.1 MPa, discharge and pressure relief are required. Long term high pressure of the LNG storage tank will affect the service life of the tank's interlayer vacuum.

　　6. LNG storage tanks advocate for vacuum inspection every year. When the LNG storage tank is a hot tank, the vacuum degree should be less than 1Pa, and when the LNG storage tank is a cold tank, the vacuum degree should be less than 0.5Pa (0.00375TOF) to be qualified.

　　7. LNG storage tanks are pressure vessel equipment. According to the requirements of the "Supervision Regulations for Safety Skills of Pressure Vessels" issued and implemented by the People's Republic of China, units with corresponding talents must inform the local quality inspection department before installing, repairing, or renovating pressure vessels. Only after obtaining approval can installation, repair, or renovation be carried out.
